Siheyuan: I eat melons while doing scientific research

Chapter 1183 He is coming, he is coming (first two chapters, two more chapters in the evening)
Lou Shouxing didn't know that he hadn't returned home yet and was already being missed, but what could he do even if he knew? He still had to go home.

Even though people joke about "shaving one's head in the first month of the lunar year" every day, the relationship between nephew and uncle has been extremely close since ancient times.

Under normal circumstances, an uncle treats his nephew similarly to his own children.

But Lou Shouxing's tricks could not be used in a short time, Gao Zhendong had to attend the meeting. As soon as he arrived at the meeting place the next day, Zhu Gong came up to him and said, "Commissioner Gao, please squeeze in, hehe."

After saying that, he sat down happily on the chair next to Gao Zhendong.

They had a very enjoyable conversation yesterday and had said almost everything they needed to say. The rest couldn't be said in the short term due to discipline, progress and other reasons, so it was time to have a serious meeting today.

But for Zhu Gong, it was rare to find someone he could really talk to, so it was a good thing to chat more. And as for the anti-submarine thing, maybe he and Gao Zhendong could create a lot of sparks when they sat together.

After the meeting started, Gao Zhendong was no longer like he had been yesterday, listening to nothing and doing nothing. Instead, he was listening carefully to the speeches of his comrades while looking at the minutes of yesterday afternoon's meeting.

It is true that he was busy discussing submarine matters with Mr. Zhu, but the minutes of the meeting taken by a dedicated person were not empty and recorded a lot of relevant information.

Gao Zhendong glanced through it and found that the comrades' main considerations were still concentrated in several directions.

First, it is to use the guided boat to reverse modification, return to its original design, remove the anti-ship missiles, add sonar equipment, and combine it with the acoustic guided anti-submarine torpedo technology from Gaul, plus the existing depth charges and rocket depth charges, and you can make a low-cost, high-performance anti-submarine boat, which can play a good role in the southern waters, the eastern waters, and the muddy sea. Don't consider the thin sea, no fool will run to this shallow plate to die.

Secondly, it is to continue the design of the latest destroyer, anti-submarine helicopters, and multiple ship-borne sonars. At the same time, it uses the Gaul L4 acoustic homing anti-submarine torpedo technology to develop its own anti-submarine torpedoes and even rocket-assisted torpedoes (anti-submarine missiles) to further enhance the fleet's anti-submarine capabilities.

The third is to strengthen the survey of underwater terrain, hydrology and other environmental conditions to provide convenience and basic conditions for the activities of one's own submarines and anti-submarine operations. This is an extremely important point. It can be said that between big countries and small countries, although they all have submarines, even if the models are the same, the difference in how they can use the submarines is huge.

Finally, on the basis of the Be-6, in accordance with the two suggestions put forward by Gao Zhendong that year, magnetic anomaly detectors and sonar buoys were developed to strengthen the fixed-wing anti-submarine patrol aircraft's ability to detect underwater submarines. After all, only this kind of equipment has the ability to search for submarines over a large area under normal unknown conditions.

The comrades are not here to just sit there and do nothing. They have considered everything very thoroughly and have exhausted all current conditions and ideas.

Gao Zhendong was watching and talking quietly with Zhu Gong.

"Well, you know what. If I were the enemy's submarine, I would also have a headache if these tactics were used," said Engineer Zhu with a smile.

Gao Zhendong also laughed: "Engineer Zhu, what I talked about with you yesterday might make the submarine party feel comfortable, but what I am going to say today might make you feel uncomfortable, so don't blame me then."

Zhu Gong was happy: "That's great, the more uncomfortable the better. It's like an exam. It's a good thing to know the test questions as early as possible, regardless of whether you can do them or not."

Gao Zhendong nodded and said, "Then I won't be polite."

He found a gap when his comrades were speaking and raised his hand.

The comrades were cheered up. Here he comes, here he comes with a lot of ideas in his head.

"In fact, comrades have already said it very completely, so I will just make a few additions. These additions may not be very meaningful at this stage because the technical requirements are high, but we cannot stop because of this. We still have to be ahead in some basic research. Submarines may not seem so deadly to the fleet, but to a country, they are deadly. Small countries generally do not face this kind of lethality. Only countries with sufficient size, technology, and political influence need to consider this matter."

As soon as Gao Zhendong opened his mouth, he set the tone. What I want to say is not very relevant to the present, but I hope that comrades can pay attention to it. As for his "lethality", although ballistic missile nuclear submarines have only appeared for a few years, there is no comrade present who does not know that this thing is really only dangerous to big countries. As for small countries, they are not willing to use this thing to attack you.

“But the combat areas of ballistic missile submarines are generally far away from our waters. No matter how much we develop now, we can’t reach that far, right?” Some comrades thought that this was a bit too far-fetched.

The combat area of ​​ballistic missile submarines is generally in their own safe fortress waters. Now the range of submarine-launched missiles is only a few thousand kilometers, which is still closer to the target area. When the range of submarine-launched missiles reaches 8000 or even more than kilometers, they will not even come close to the door of the target area.

Gao Zhendong shook his head: "One day, we will urgently need to grasp the movements of every enemy nuclear submarine, either for self-protection or for attack. Even if it is for our own submarines to safely launch weapons, we must clear all enemy attack submarines in the fortress sea area or forward launch position we have set up for our submarines. Therefore, the construction of anti-submarine forces, even if it is only the construction of anti-submarine forces in our own waters, is very important."

During the Cold War, silent fighting between nuclear submarines underwater was the norm, although there were no major consequences. Gao Zhendong's idea was simpler. At least the southern waters or the muddy sea must be kept safe, right?
Especially when he knew very well that in the next few decades, what we have to consider is not to attack more than 1 troops to the other side of the earth, but only to attack a few thousand troops to the other side of the Eurasian continent, the Hunhai area becomes important.

Moreover, in that situation, the opponent we actually need to guard against has almost only one way to threaten our submarines in the muddy sea, that is, submarines. As for surface ships, it would be a bit too much for the opponent to think about it.

Geopolitics is changing, and the opponents we face are also constantly changing.

Gao Zhendong did not say all these words, but the Navy and the Defense Work Committee knew what was going on. They just didn't know that things would develop to such an extreme.

"Yes, that's right, Comrade Zhendong, just tell us what you think." The navy leader said with a smile.

"Okay. Let me say this first. In the near future, the only two methods we can vigorously develop and that can be supported by technology are still sonar and magnetic anomaly detectors. And magnetic anomaly detectors are a fast, wide-area, non-contact form of anti-submarine detection, so they must be vigorously developed."

Gao Zhendong actually knew more than just these two anti-submarine methods, but from a technical perspective, he could only give priority to these two for now. Needless to say, sonar, no matter what form it is, at least the principles and practical technology have been obtained, and the conditions for implementation and even maturity are available.

The magnetic anomaly detector is the non-contact submarine search technology with the best comprehensive capabilities. Not to mention now, even decades later, countless anti-submarine patrol aircraft will still have a long stick on their butts. It has almost become the identity mark of a serious anti-submarine patrol aircraft. You don't need to recognize the model, you can know what this guy does by looking at the long stick on the butt.

"Well, we understand that the magnetic anomaly detector is very excellent. But when faced with non-ferromagnetic materials or a demagnetized hull, isn't it a little powerless?" This is Engineer Zhu. Submarines are his specialty. He asked this question not to argue, but to consider various possibilities.

"Even if the shell is made of titanium, it is impossible for the interior to be made of titanium, right? Demagnetization is impossible to completely demagnetize, and when ferromagnetic materials pass through the earth's magnetic field, the induced magnetic field will still cause distortion of the earth's magnetic field, which cannot be solved by demagnetization. The only problem is that the sensitivity of the detector is required to be relatively high."

In order to deal with magnetic mines, both surface warships and submarines have demagnetization operations, but submarine demagnetization is not just for dealing with magnetic mines, but is a bigger game.

"Well, you have a point. Similarly, sonar buoys, as a semi-contact submarine search equipment that can accurately locate targets, must also be vigorously developed?"

Gao Zhendong nodded: "Yes, for anti-submarine aircraft, the positioning accuracy of the magnetic anomaly detector is high, but it is still limited. According to the current and future technological developments, the search distance of the magnetic anomaly detector is about 300 to 500 meters, depending on the type of submarine and the depth of the ocean. This distance is related to the water depth, but not much, and it mainly depends on the distance. The positioning error is about 200 to 300 meters."

This data was copied by Gao Zhendong and is a typical "desensitized" data. The actual data is definitely different from this, but it will not be worse than this.

Considering that the current technological level cannot be compared with that of a few decades later, it is still appropriate to use this data for planning and reference.

Gao Zhendong's words made the comrades more clearly aware of the benefits of the magnetic anomaly detector, and also made Zhu Gong feel under great pressure. This search distance and positioning accuracy are already very dangerous for submarines.

For the comrades in charge of anti-submarine operations, on the contrary, this accuracy is sufficient to launch anti-submarine strikes, especially after having acoustic homing torpedoes, which can find targets by themselves.
